Specifications include, but are not limited to: 1. Disconnect and demolish existing UAC units, refrigerant and heating piping, and any associated electrical or low voltage control wiring. a. This project includes removal and replacement of UAC #1, UAC #2, UAC #3, UAC #4, and their associated condensing units. 2. Disconnect and demolish the (4) existing condensing units. 3. Existing UAC units should be drained of any remaining R-22 refrigerant. Please include in your scope the costs for draining and disposing of all existing equipment, piping, refrigerant, needed to be able to provide new UAC and condensing unit system. 4. Existing equipment pads are to remain unless new pads are required to support the new unit. If larger equipment pads are required, please include in your proposal. 5. Disconnect and replace any existing ductwork required to install the new units. The goal is to keep as much of the existing ductwork as possible. 6. Provide new UAC units with condensing units to replace existing UAC #1, UAC #2, UAC #3, and UAC # 4. Please note that the existing units are manufactured by Carrier and your base bid should be for replacement with new Carrier units. The new units are to match the voltage of the existing which is 208v, please verify during the mandatory site walk. An alternate manufacturer can be proposed, reference pricing in section below. 7. New units are to be sized appropriately based on the existing conditions and square footage. 8. UAC #1 and #2 have an existing humidification system that need to be re-piped to the new units. 9. Existing equipment tag numbers are identified in the photos shown in the proceeding pages. 10. Please note that it’s assumed that most of the existing piping cannot be re-used and that new line sets will need to be run. a. The lines sets for UAC #3 and #4 will require surface mounted piping on the outside of the building with a painted metal shroud/cover. These line sets will need to run from the ground level up to the 3 rd floor. The metal shroud should be painted to match the existing building exterior. Reference attached photos for this condition.
